  1. Automated Printing on A1 Mini Tutorial
  2.  
  3. ***Disclaimer: This could potentially damage you printer as every machine can have different version, however updating firmware and watching the first tries closely will likely not cause any problem. Use it at your own risks***
  4.  
  5. PRINTS MUST BE PLACED ON THE RIGHT SIDE OF THE PLATE, AS CLOSE AS POSSIBLE TO THE A1 MINI ARM, AT Y=100MM maximum (world coordinates)
  6.  
  7. Safe: Print a small 5cm tall, 4mm thick cylinder with 2mm outside brim to test first
  8.  
  9. Using https://makerworld.com/fr/collections/6408035-print-automation mount and a custom built .gcode generator I made a system to automate print on my A1 Mini as well as speed up the overall process
  10.  
  11. #1: In BambuStudio:
  12.  
  13. Create a custom printer profile, Click on the little grey pen to edit your printer profile (ONLY TESTED on A1 MINI).
